LIQUID PROJECTING DEVICE z'sheets-sheet 2 Filed Dec. 4, 1955 gra/WMM@WM5/eww;

Patented Apr. 27, 1937 UNITED STATES ement lOFFICE The present inventionrelates to the same general subject matter as my Patents No. 1,923,979and No. 1,983,461 respectively grantedrAugust 22,

1933 andDecember 4, 1934, for Liquid projectingV devices.

The devices of both said patents are rather sensitive and easily set olfor discharged by application of pressure to the body practically at anypoint between the ends thereof and thus are not of such nature thattheymay be confidently car- `ried about the person, as in a vest or coatpocket or carried loosely in a vehicle `or truck, or carelessly handledwithout risk of accidental discharge. While the above mentioned factsuits them admirably for the particular uses described in said patents,it limits the useful field of such devices, and prevents their Yuse bytruck drivers, pedestrians, individual passenger car operators and thelike who, except for such risk of accidental discharge, would prefer tocarry such a device in a suitable clip or holder arranged at a suitableposition in the truck or car or in a coat or vest pocket about theirpersons.

This invention has for its primary objects to provide a liquidprojecting device of the general construction above referred to which issafely portable about the person and which will withstand carelesshandling and yet be extremely sensitive to be discharged by pressureapplied at the right point; to provide a projecting device,corresponding in construction to either of the above referred topatents, With a strong protective casing protecting it againstaccidental discharge by the accidental application of pressure, saidcasing being so formed as to leave openings therethrough wherebypressure may be intentionally applied directly to the sides of theliquid containing casing; to provide a primary liquid projecting devicewhich may be used With paper currency or simulation of currency in themanner described in said patents or may be used in association with theprotective casing herein described so standardizing the size of thedevice in manufacture, 45 though this is not essential to my inventionin its broader aspects; to provide a liquid projecting device of thecharacter and attributes mentioned with a protective casing and, as soassociated with said casing, of such size, form and construc- 50 tionthat it may at will selectively be used in a bundle of money or betweenpaper currency or papers simulating currency as described in my saidpatents or may be safely carried in a coat or vest pocket about theperson kor may be carried in a 55 spring clip or other holder located ata desired ing tube being shown in elevation;

point in a truck or car, though` this also is not essential to myinvention considered in its broader aspects; to provide a liquidprojecting device of the general construction referred to with a'protecting casing and of such size, shape and finish or outer coveringas to closely simulate one wellknown fcrmof pocket-book or wallet.Merely for purposes of illustration of my present invention Ihaveelected to show in the embodiment of my invention herein illustratedthe 10 specific f rangible closure and cooperating constructiondisclosed in my Patent No. 1,983,461 granted December 4, 1934, itbeingunderstood, however, that my present invention is not limited thereto,but may'equally well be used with any 15 other pressure operated valveor closure construction Acapable of serving the function.

In Figures 2 and 3 of the accompanying drawings the present preferredform is drawn to actual full-size scale, with the exception that thethickness of the walls of the liquid containing and projecting element,the paper Il, the protective plates I5 and the outer covering I8 aregreatly exaggerated in order to show the same clearly;

Referring nowl in detail to the drawings, the liquid containing andprojecting device or element per se will preferably be constructed. inVaccordance with my Patent No. 1,983,461, and thus will have a rear endplate I1, Side' members 3 and 4, a front end plate G and closure meansassociated with the latter.`

The rear end plate I will. be formed with' an internally screw-threadedbore extending from. its rear face and communicating with a reduceddiameter. Vsmooth bore 2d to forni az charging opening through. said.platev If, whichopening 'is closed,A after the device been lled: withthe?V liquid or` gas, by' screwing ina plug 2r until its'. front endseats against the conical `Seat at the juncture of theI twct boresV andyits rear end lies inward of the rearA face; of plate I, after which the'rear end'of said screw-threaded bore is to 'be ll'ed. with. solder orother suitable filler to make' a perfectly gas-tight closure, andthere'- after` thel solder or filler is preferably ground on led. downflushY with thev rear face of plate I. block or` front end plate (i`ispreferably formedl with; a centrally disposed cylindrical socketextending from. its rear face partially through.' said: plate 6topreferably snugly receive the tubular portion: 'If of the frangibleclosure means which has integral therewith a longcurved tail or shank8i, the tubular:V portion 'IS beingpartially-i cut through. or' nickednear its 'rear end-f as at 9.1fromits'extericr'face. Aninternallyscrew-threaded boref concentric with said cylindricalv socket extendsfrom the Vfront face of the' block or plate 6 tof theV said cylindricalsocket and: an= externally screw- "thr'eaded discharge or projectingtube I!! screwed into' said' screw-threadedl'bore has its` interior incommunication with the interior ci the tubular-part T .ot said frangibleclosure means.

The tubular portion, 1: will' be secured in its cylindrical socket in.any suitablef liquid and gas-tight manner, as forinstance by applying tothe exterior ot said p'ortiorr I or to the wall of .said socket, orboth, any' suitableI cement that will stand the heat incident toy thesoldering of the block or front end plate 6 in thefront endl ot thecasing and will resist the action 'chemically of the: chemicals employedin the containedy liquidc or gas selected; v' The spring I'I of suchvmaterial asv will; resist tlefaction off the chemicals employed in theyliquid: or gas. used' is. normally under tension. with its outer endanchored in a recess or socket I2 in' theffrlont plate- Ir ari-df itsvinner end? |13: hooked yor looped: around' the flattened shank 8- of theefrangible closure element immediately to the rear of tubular'portiont Iand by the somewhat flattenedi form `of the loop t3" serves to preventanyl tendency of the frangible element to: turn 70 about the axis` ofits tubular portion 1 and to pull the fractured part of the closuremeansY out fof'alignment with thepart oftheV tubular" porti'on 1retainedl in the cylindrical socket. While it isi preferred to?provide 1such. a'. spring I'I- serv- .75 ing the above' functi'onsv orE thelattetfunction,

even where a frangible closure is employed the provision of the spring II or other means serving one or both of the functions mentioned is notessential.

The end plates or blocks I and 6 are to be of 5 the same size and shape,being elliptical in shape transversely of the liquid containing elementas a whole, and are to be soldered in the rear and front endsrespectively between the respective opposedl faces of the respectiveendY portions of 10 the sides 3 and 4, and the side edge. portions ofthe side 4 are lapped over against and soldered or welded to the opposedouter faces of the marginal portions of side 3.

Asthuslconstructed the liquid or gas contain- 15 ing-andv projectingelement is preferably wrapped or covered with preferably but one layerof thin paper; textile orA other friction producing and rattle or noiseVpreventing covering II, after which the protecting plates I5,preferably of 20 relatively thick stiir tempered steel capablel .of

Vwithstanding sharp'f blows and great pressure withoutbeing. deformed`and Without transmitting'. such blows'or pressureto thesides 3 and/or 4of the liquid or gas container per se areap- 25 plied over the sidesthereof and secured in such position in any suitablev manner.

Such plates I5. are to. be as long asv the. portions o-f the sides 3`and 4 between the opposed faces of the. end blockson plates I- and 6 and30 preferably will be of such length as to. receive between theirrespective opposed end face portions said plates I and 6L,

As arranged about said, liquid container the two opposed'Y plates I5'will have marginal sub- 35 stantially straight or flattened' flanges orportions lying in engagement with each .other and from saidv marginalflanges will' define between them in cross sectionv an ellipse"corresponding in shape to the elliptical cross section of the, 0 liquidcontainer and of such size in crossY section as to snugly receive thebody of the liquid container with a` suciently tight .or snug fit to setup a friction'al contact with the rattle preventing covering vI'I toyprevent rattling' orA loose relative movement, while at the same timenot exertingA substantial compression on the sides 3 and/or 4 of theliquid.v container.

In theembodiment illustrated in Figures l to 7 a rear'molding blockl Ilhaving a fiat front face and being slightly' wider and thicker than rearplateA I and a front molding block 6' bored to fit over the projectiontube Ill andl corresponding in size and shape to rear molding I areapplied respectively to the rear' and front 55 faces of the end blocks landl B respectively; The protecting platesv I5 are then applied to therespective sides .of the liquidv container with their endedgesinengagement with theopposed faces or shouldersY of' the molding blocksI and 6', 60 which preferably are of metal, and' said end edges andopposed faces 'or shoulders may be solderedv orl welded' together, asmay the opposed engaging' flattened marginalY flanges or portions of theplates I5, and thereafter the outer covering or camouflage dress,preferably a suitable leather' such as sealskin or some such similarmaterial I8, or simulation thereof, as is commonly used for Vwallets orpocket-books is smoothly and` preferably tightly applied over` each faceofthe device as thus assembled, that is, o-ver the' outer faces of theplates I5 and moldings 'I" and 6 and has its marginal portions securedtcgether in any strong securesui-table manner,as by cementing or bystitching as@5 indicated at I9,V the projecting nozzle Ill projectingbeyondV such securement means with its front end unobstructed.

If desired, in the embodiment immediately K above described,`thesoldering or welding of the plates I5 to the molding plates or blocks I'-and 6 and to each other may be dispensed with, in which case reliancewill be had on the covering materialV I5 and its connecting or securingstitching I9 or cement or other connecting means to lthe side 3 of theliquid container most closely approached by the shank 8, leaving` lthesides 3 and 4 uncovered for the intentional application of pressure forthe full area of the openings I6, but

such uncovered portions of Vthe sides 3 and '4- will lie laterallyinward of the outer faces of the plates I5 and be protected againstdirect blows or deformation as a result of any except the most unusualaccident, so that even though the device be accidentally dropped andstepped on or run over it will not be discharged.

The device as thus provided with its protecting plates I5 and outercovering I8 will preferably be made of a width not substantiallyexceeding the width of paper currency and of an overall lengthpreferably slightly less than the length of paper currency and will beof iiattened elliptical shape in cross section so as to be relativelythin whereby it may be either used in association with a bundle, or aplurality of bills of currency to constitute a camouflaged defensiveweapon in simulation of the usual unloaded bundle of currency or may beslipped in a pocket by itself or in a spring clip or other holder andused as a defensive weapon, either with the added element of surprisewhen handled or treated as a wallet in case of a surprise hold-up, or asa straight out weapon where there is sufcient warning to get it out andready for action.

Preferably the arc of each of the sides 3 and 4 y will be struck on afour inch radius and the width of said sides as arced and assembled willbe one and seven-eighths inches and the greatest width between theopposed inner faces of said sides 3 and 4 will be approximatelyone-fourth of an inch and the sides 3 and 4 will be of very thin butrelatively stiff resilient sheet metal whereby when pressure is appliedto the area uncovered by the walls or plates I5 as dened by the openingsI6 in said plates I5 the pressure will be exerted over a wide area ofsaid walls 3 and 4, resulting in putting the contents of the containerunder very high compression.

In the modification illustrated in Figures 8 to l inclusive, theconstruction and operation are the same as in the preferred form exceptthat the molding blocks i' and 6 and the leather or other covering I8with its stitching I9, and the paper or other noise or rattle preventingand friction producing wrapping are dispensed with, the liquid containerbeing slipped by itself between the protective plates I which have theirend portions extended beyond the end plates I and 6 and bent toward eachother and provided with engaging end flanges, the end flanges and thevside marginalflangesbeing secured together at suitable intervals as byspot welding indicated at Illa, the front endfofthe plates I5' beingvmedlally suitably bent or arched away fromfeach other as'at |513ltoac'commodate the projectionA tube IIl and leave its forward endunobstructed.

Of course, in both forms illustrated, application of pressure to theportions of sides 3 and 4 left uncovered by the openings I6 in theprotective plates results in breaking the frangible closure and thedischarge of the contained liquid through the projection tube ID, inaccordance vwith the teaching of Patent No. 1,983,461.

Either formfillustrated may be safely carried lready for instant use,either aboutthe person as inthepocket B of a coat or` vest A as`illustrated in Fig. l or in. a spring clip or other holder E servingthe same function and lmounted as by hooks F at rany desirablelocation'in an automobile truck or passenger car orA other vehicle, asfor instance by being hooked into the front of the drivers seat D.
